Google Translate..An explosive device thought to be a hand grenade was detonated at the city hall building of Matamoros, Tamaulipas Wednesday, according to Mexican news accounts.
The attack took place at about 1015 hrs today in front of the building. Two unidentified female passers-by were wounded in the explosion.
The mayor of Matamoros, Erick Silva Santos, was not in the building at the time of the attack.
The last hand grenade attack in Matamoros preceded a major intergang and gang versus military confrontation last September 15, when a grenade was thrown into the offices of the Procuraduria General de la Republica (PGR), the Mexican national attorney generals office.
No one was reported hurt in that attack.
